Born in 1937 in San Sebastian, Spain.
Lives and works in Paris, France.

Esther Ferrer is chiefly know for her performances, her main form of expression, alone or in the group Zaj created by Juan Hidalgo, Walter Marchetti and Ramon Barce, from 1967 until its dissolution in 1996.
Her work has always been more orientated towards art/action, an ephemeral practice, rather than towards art/production. That was how she founded with J. A. Sistiaga, in the Spain of the early sixties, the first “Atelier de libre expression” (Free expression workshop).
From the seventies onward, she has devoted part of her activity to the visual arts: worked-over photographs, objects, models, installations and paintings based on the series of prime numbers. Her work is inscribed within a very specific minimalism that could be defined as the “rigor of the absurd”. She says, but only when asked, that every performance is the “art of space, time and presence”.

She represented Spain in the Venice Biennale in 1999, and was awarded four prizes in Spain: the Velazquez prize in 2014, the Premio Nacional de Artes Plásticas in 2008 (National Prize for Visual Arts), the Premio Gure Artea in 2012 (Basque country) and in 2014, the Premio MAV - Mujeres en las Artes Visuales (Women in the Visual Arts). Ttwo retrospectives were shown successively in France: in the Frac Bretagne in Rennes, from January through April, 2013 Le chemin se fait en marchant / face A and in the Mac/Val in Vitry-sur-Seine from February through July, 2014 Face B. Image / Autoportrait.

Following those two exhibitions, a monographic work, the first in French (and in English), retracing her performances and her installations, was published jointly with the Frac Bretagne and the Mac/Val.

Four solo exhibitions by Esther Ferrer took place at the Lara Vincy Gallery: The poem of prime numbers in 2002, Within the framework of art (3) in 2009, Structure and space projects in 2014 and Un peu de tout mais bien ordonné in 2021.
